And here are my compiles from Reduce variation in rootDepth between different threads  8d858783e1bcf4266f30614c0f69677835976a22

The binaries are 'Windows', done on GCC520 posix seh       make profile-build ARCH=x86-64-bmi2 COMP=mingw       and      make profile-build ARCH=x86-64-bmi2

[A] Static (no lto no libs required)  https://www.dropbox.com/s/aja7lrpa08evoom/stockfish_301015_x64_bmi2.exe?dl=0

[B] LTO (no static libs must be with binary)   https://www.dropbox.com/s/n2767f7di2dz6vl/Sf%20flto%20dll%20must%20be%20with%20exe.zip?dl=0

Both are also attached here.  

This is how these bench against abrok builds

[A]   Base = abrok    Test = Static (no lto)

Results for 10 tests for each version:

                    Base         Test           Diff     

    Mean    2889703   3021925   -132222  
    StDev         4520         6155        7911     

p-value: 1
speedup: 0.046 (4.6%)


[B] Base = abraok     Test = lto (no static)

Results for 10 tests for each version:

                    Base          Test          Diff     

    Mean    2895240   3085054   -189814  
    StDev         3520         7303         9335     

p-value: 1
speedup: 0.066 (6.6%)

We are very near to qualify for TCEC superfinal.

This is a great result!

For the superfinal we have to provide to Martin some optimized binary (few days in advance), otherwise he will fallback on the abrok ones.

So I would ask interested people to please provide a binary faster than the abrok defaults.

I guess we can use current master version, there is some work on lazy formula for 24 cores, but I am not sure it will end up in time (few days before final, so within tomorrow, more or less).
